About Birch Water by Lotte Tisenkopfa-Iltnere, Founder of MADARA All about Birch Water By Lotte Tisenkopfa-Iltnere, founder of MADARA With the outbreak of spring, birch trees across the Northern hemisphere prepare themselves for blossoming by running an energising liquid - known as birch water, sap or juice - throughout the tree from the roots to the buds. Why does birch water flow at all? Birch water is a nutritious liquid that birch roots vigorously push into the trunk, moving it upwards to the branches where it finally reaches its destination – the buds. The juicing process is necessary for the tree to ensure intensive growth and regeneration after the freezing winter standstill. It rapidly spreads nutrients across the body of the tree, boosting cell division, leaf unfurling, blossoming, and most of all - growth. What’s in birch water? Birch water is generated by the roots. Roots take water and minerals from the soil, while carbohydrates (sugars) formed in the previous summer by photosynthesis are accumulated and stored in the roots. Besides minerals like potassium, magnesium and calcium, the sap contains a unique blend of amino acids (citrulline, glutamine, glutamic acid, asparagine, isoleucine, phenylalanine), enzymes and natural fruit acids (malic acid, succinic acid, citric acid and fumaric acid). When does it flow? The flow of sap is triggered by rapid temperature changes. Night temperatures should fall below zero but the day should be warm and sunny. The birch tree senses the freezing and thawing of the soil and launches a cascade of natural processes that result in the flowing of sap. The flow continues for just one to two weeks and the fresh green hue of unfurling buds marks the end of birch water harvest and the onset of spring. The time of the year when birch trees generously share their nutritional sap with us humans is different across the Northern hemisphere. It might be the beginning of April in Latvia or Southern Finland and it can be as late as May in territories closer to the Arctic Circle. Traditional use of birch water Harvesting of birch water is a tradition of nations living in the Nordic region. It is used primarily as a health drink to detoxify the body, improve health, clarify skin and strengthen hair. Fresh water is used for cooking. Birch water starts fermenting after a day or two, so it is used to make sparkling soft drinks or even birch wine. Birch water INNOVATION – the new anti-ageing ingredient Cosmetic manufacturers are continuously searching for new active ingredients for product development to satisfy consumer needs. Among anti-ageing ingredients there is demand of natural substances with well characterized chemical composition and proven efficacy. The first of its kind scientific study on birch water was launched by the University of Latvia and organic skincare producer MADARA to investigate effects of birch water on skin. Historical medical records highlight positive effects of birch water both nutritional and topical use; however no proven mechanisms of action on skin have been characterized before. This study focused on elucidation of birch water’s effects on skin cells in vitro . Birch water’s potency to stimulate dermal and epidermal cell proliferation, delay of cell senescence, in vitro protection against reactive oxygen species, and promotion of growth factor secretion were tested. The findings of the study indicate that birch water has a significant anti-age activity. As confirmed by cell cycle analyses and cell proliferation (growth) analysis, birch water speeds up dermal cell regeneration by 25% compared to control (graph 1). In presence of birch water skin cells show significantly lower accumulation of aging markers, indicating that nutrients present in birch water make skin cells stay functional and healthy for a longer period of time and are able to actively synthesize essential youth Graph 1.

Data represented as relative changes in cell proliferation activity compared to control. Control level of cell proliferation (100%) is depicted with dashed line. * p-value < 0.05, n=3 (ANOVA). Another significant finding indicates that birch water has strong antioxidant effect, reducing negative impact of environment such as pollution and UV rays. Study showed that dermal cells previously treated with birch sap are considerably more resistant to oxidative damage and there is lower accumulation of free radicals (Graph 3). Birch water is a powerful free- radical scavenger, helping to neutralise aggressive oxygen molecules and repairing damage done to skin cell’s DNA. Control (high oxidative stress) Birch Water 10% (reduced ox.stress) Birch Water 50% (reduced ox.stress) Graph 3. REDUCTION OF OXIDATIVE STRESS. Blue light illuminates skin cell nuclei. Green marker indicates oxidative stress. Research concludes that similar to its activity on the tree promoting the growth of young leaves, birch water speeds up regeneration of dermal and epidermal cells, making a powerful cellular anti-age ingredient. Antioxidant properties of birch water reduce the negative effects of photo-aging, environmental pollution and consequences of inflammation. Strongest stimulating and skin protecting effects of birch water were established at high concentration of sap, indicating that a skincare product with at least 50% of birch water will provide age-defying and damage-reversing benefits and suggesting that replacing regular water with birch water maximizes rejuvenating properties of a cosmetic formulation. Chemical analysis of birch water In a recent study aiming at characterising the chemical components of birch water (The University of Latvia, 2017 ) 55 biologically active compounds were separated from Birch sap. Most dominant peak with retention time at 1.49 min contains a very polar fraction of birch water, including three organic acids succinic acid, malic acid and citruline (represented about 6.7% of the total amount), five amino acids and phenolic compound metabolite tyrosol 4- sulphate (represented about 32.6% of the total amount). Overall nine different amino acids were separated from birch sap and represented about 16.8% of the total amount, including leucine (2), isoleucine (3), glutamine, phenylalanine. It should be noted that organic acids and amino acids separated from our Birch sap sample are widely distributed and described in the birch sap products. It was found that Birch water is not very rich with phenolic compounds, but some of them were spared such as homovanillic acid (4), (+)-catechin 3-O-glucose (6), resveratrol 3-O-glucoside (8). Birch sap contains betulin (7) which represents about 2,4% of the total amount and some undidentified tannins. Graph 4. Base Peak Chromatogram (BPC) of the Birch sap.

Brief history of birch water and its historic records With the first medical records dating back a thousand year, harvesting and consuming birch water is a remarkable tradition of folks living in the subarctic regions of Northern Europe. German abbess, writer and philosopher Hildegard von Bingen was the first to document the healing properties of birch in 12 th century in PSYSICA, encyclopaedic book on healing plants. Italian botanist Pietro Andrea Mattioli praised medicinal effects of birch water in 1561 and Estonian physician Johannes Raicus praised birch sap, comparing its healing properties with those of mineral water in 1631. Danish botanist Simon Paulli describes birch water in 1648. Birch sap has also been used for medicinal purposes and was included in the “Danish pharmacopeia” in 1772. Swedish cartographer Olaus Magnus made a brief note in 1555 that Scandinavians were tapping birch for sap and using it as a fresh drink. Ethnographical records from various provinces give detailed information on the gathering and manufacturing of the sap into drinks or its use as an ingredient in various food stuffs. In Finland and Carelia birch sap was tapped off in the spring and used as a refreshing drink. The Saami in Finland also made a refreshing beverage of birch sap In the Norwegian medieval “Flatey book” (“Flateyjarbók”), completed in 1394, there is a description of how King Sverre and his men “spent two nights in the wilderness and had no food but sap they could suck from the trees” In Latvia and Estonia month of April known as “sulu mēnesis” (in Latvian) meaning “birch sap month”, indicating that sap usually flows and is gathered in April. Records of traditional medicine indicate that birch water helps to treat in prevent several diseases, like stomach diseases, kidney stones, colds, deficient liver function, scurvy, headaches, skin diseases. Birch water was widely used both by the peasantry and the nobility. The tonic, revitalizing and nutrient properties of birch have been mostly appreciated after winter, when human body was weakened by the long period of winter and deficiency of fresh produce. Most of the sap produced has been used as a fresh drink, but in some areas they added yeast, and in more recent times also sugar or other aromatic plants to produce a variety of refreshing drinks or a kind of wine. .

  • Harvesting Birch
    UAMN Virtual Early Explorers: Water Harvesting Birch Sap A delicious way to explore water in spring! OneTree Alaska is offering two at-home citizen science projects for children in grades K-12 (inquire about younger children). See information below. The “Tapping into Spring” project is providing free birch tapping kits (while supplies last) for families to use at home, through the FNSB School District. The kits are also available to purchase for $25. Instructions and video tutorials are provided. If you are interested, please read the information sheet below, then contact your teacher (K- 12) or Jan Dawe at OneTree Alaska: [email protected]. Photo by Andy Padilla Before all the snow melts, birch trees start producing sap. In the two or three weeks before leaves come out, we can harvest this sweet sap. Watch a video to see how it is done: https://www.youtube.com/watch?v=Sw9JWSum5fs There are two ways you can enjoy birch sap: 1) Drink sap straight from the tree. Birch sap tastes similar to water, with a slightly sweet flavor, and is rich in minerals. 2) Boil the sap slowly to make birch syrup. Birch syrup is tastes great on pancakes, but takes work to produce. If you are ready to try making syrup, contact the staff at OneTree Alaska and they can guide you through the process. Citizen Science Month at Home Be a citizen scientist from the comfort of your own home! OneTree Alaska is offering two projects in honor of Citizen Science Month, each appropriate for students of all ages—plus their families and friends! To participate, let your child’s teacher know of your interest By the end of the day on Monday, April 13, 2020.

  • Final Report for Pre-Dissertation Fellowship
    Community Forestry Research Fellowship Final Report for Pre-Dissertation Fellowship Assessing the Role of Non-Timber Forest Products in Interior Alaska Communities Kimberley Anne C. Maher University of Alaska Fairbanks Research Focus and Goals The harvest of non-timber forest products (NTFPs) is a prominent activity in Interior Alaska for both personal and subsistence uses. A survey conducted in 2004 showed that one–third of households in Alaska’s Tanana Valley picked wild blueberries and one-quarter of the households harvested firewood (ABFC 2003). A few niche industries in Alaska are based off NTFP resources such as birch syrup production. The birch syrup industry is almost two decades old. Alaskan birch syrup has created quite a buzz and has an unsatiated global market demand (Pounds 2000). Demand for birch syrup is growing (Cameron 2001), and it is a unique forest product that piques the interest of people ranging from tourists visiting Alaska to food connoisseurs (Jackinsky 2001). The number of birch syrup operations in Alaska increased during the 1990’s (ABFC 2005) but has since has declined with only two operations producing birch syrup in 2007. Little data is collected on NTFP harvest practices in Interior Alaska so forest managers do not have a clear idea about (1) who is collecting NTFPs (2) what NTFPs are being harvested, and (3) what non-market and non-tangible benefits people are also seeking and receiving from their harvesting practices. Therefore my research questions are: 1. Are forest management plans needed for personal-use NTFP harvesting? Are people’s current expectations for NTFP harvests being met under the present management? 2.

  • Gathering Birch and Birch Bark
    Birch and Birch Bark by John Zasada, USDA Forest Service All species of trees that we most commonly think of as "timber species" have potential commodity values, often referred to as non-timber forest products (NTFP) or special forest products, that are not necessarily related to wood and fiber products. Some of these NTFP values are recognized and commercially important and others are secreted in the history of Native Americans and other people who at one time in their past depended on natural products for their physical and spiritual well-being. Paper birch is one example of a species that was an important part of Native American culture and has considerable potential for NTFP. Before discussing NTFP from birch, we need to consider the potential for multiple products from this tree and from birch forests. The diagram below illustrates the potential product available from a birch stand as it develops through time. Admittedly, this is an idealized view of the potential. However, there are examples of uses of birch for each of the products indicated in the diagram. There has never been a plan to attempt to harvest all of these products from birch trees and stands in the same geographic area. Northern Minnesota, Wisconsin, and Michigan would provide a good area to test these ideas. The two main products harvested from birch without killing the tree are sap and bark and, to a very minor extent, the roots. The method of collecting birch sap is generally similar to that of maple. Birch sap differs significantly, however, from maple in that it has simple sugars (glucose and fructose) rather than the more complex sugars of maple (sucrose).
